Misfire at full boost

Splinter · Post by **Splinter** » Fri Jun 30, 2006 2:18 am

I just turned up my boost back up (first time since the tranny swap) and Ive noticed a weird misfire feel at full boost

Its somewhat reminiscient of when I had a slightly loose sparkplug and the spark plug boot was getting blown off, but not as violent

Possibly the spark is getting blown out? Should I go to a colder range?

I'd start with checking the gap and condition of my plugs. Replace them to see if that helps.

better a misfire than a ping.

And check the wires. Make sure they're okay and that they're firmly snapped onto the plugs.

depending on how much boost, you may want to run a smaller gap.

No he has wasted spark ignition. But it does sound like it might be he coil.
